Spinosaurus!

I have recently discovered that there was a bigger carnivorous dinosaur than the giganotosaurus... the spinosaurus! I've known about the spinosaurus, but I didn't know it was bigger than the giganotosaurus (not to be confused with the gigantosaurus, that's a completely different dinosaur). Spinosaurus' arms are less ridiculous than Giganotosaurus, but instead it has a spiny ridge on its back (hence the name) which just makes it look all hunchback. Other than that it is rather fierce looking. I wonder who would win in a fight? Giganotosaurus or Spinosaurus? or what if it was Giganotosaurus vs Tyrannosaurus Rex vs Spinosaurus vs Allosaurus? We'll never know.
